The Colgate Optic White Advanced LED Whitening Treatment is available for $185 — which sounds like a lot, but it's actually a small portion of the price you'd normally pay the dentist to whiten your teeth six shades.

The innovative kit includes the device, a 10 day treatment, and a charging case. Colgate also offers subscription options for those interested in keeping up with the whitening! Most people repeat the cycle every three months — note that if you do this, you only need to repurchase the serum, not the entire device.
